Comment Re: What about random read performance? (Score 2) 38

As bad as their random-read performance is, their random-WRITE performance is usually much, MUCH worse.

You get a massive speed increase if you switch to a better filesystem: btrfs or f2fs.

git reset --hard: 3m45s btrfs, 3m55s f2fs, 12m30s ext4, 16-18m xfs (huge variance)
"./configure && make -j4 && make test" of a shit package with only ~2MB of persistent writes: f2fs 95s, btrfs 97s, xfs 120s, ext4 122s

(class-4 card in a Pine64)

And almost none do their own wear-leveling, so a Linux swapfile can literally max out the lifetime writes of a microSD card in 1-3 months

Not SD but eMMC: Samsung's fancy-schmancy eMMC cards are apparently made by someone no one told about the write endurance problem: I've been running Debian archive rebuilds and other I/O-heavy loads since early 2013 on a 64GB card ($89) in an Odroid-U2, and despite me heavily overcommitting memory (ie, heavy swapping a lot of the time), the card is still going strong.

The amount of voter fraud in the United States is exceedingly low so the whole voter ID laws are a solution in search of a problem.

Voter ID laws solve a very clear problem, just not the one their proponents claim.

There is also widespread evidence that such laws are designed to target democratic voters and that they tend to target the poor and minorities.

Yep, that's the problem: blacks, latinos and white trash voting too much. Voter ID isn't a complete solution, but it's a useful step. I'm sure Bannon has some ideas about the final solution.

Hmm... maybe that is what Trump meant when he claimed three million "illegals" voted for Hillary. He meant "people who shouldn't be allowed to vote", rather than "people who aren't citizens", the way the silly media interpreted the words.

Submission + - Scientists Seek To Reinstate Pluto As A Planet - And Many More

Rei writes: After several years of publicly complaining about the "bullshit" decision at the IAU redefining what comprises a planet, New Horizons programme head Alan Stern and fellow planetary geologists have put forth a new definition which they seek to make official, basing planethood on hydrostatic equilibrium. Under this definition, in addition to Ceres, Pluto and other Kuiper Belt objects, large moons like Titan and Europa, as well as our own moon, would also become planets; "planet" would be a physical term, while "moon" would be an orbital term, and hence one can have a planetary moon, as well as planets that orbit other stars or no star at all (both prohibited under the current definition).

The paper points out that planetary geologists already refer to such bodies as planets, citing examples such as a paper about Titan: “A planet-wide detached haze layer occurs between 300-350 km above the surface; the visible limb of the planet, where the vertical haze optical depth is 0.1, is about 220 km above the surface”

You seem to be saying "We don't have them today, therefore it won't be soon." I'm not sure that's a valid argument. Or maybe you're banking on the TWO DRIVERS thing. Do you think it would be sooner if they had only one driver? Or maybe having TWO DRIVERS is what it took to get somebody to allow them to do it? Either way, I don't see how they are a joke.

Comment Depends on supervision (Score 1) 125

It's not a terribly difficult problem to get to work 99.5% of the time, but with lives at risk most people aren't too happy with that number.


If the system works even 90% of time and there's a human backup that is alert and focused, then it's good already.

(like autopilots found in airplanes, boats, some modern high-speed train.
Autopilots help automating some minute detail of the driving/sailing/flying.
But autopilots are still under the supervision of a human in charge.
It just relieves the human of part of the stupid hard gruntwork.

That's also were Tesla's autopilot and Google's prototypes on highway fell in).

If the system works even 99.9% of time, and the human is asleep, that's an entirely different can of worm.
You need well established public awareness that the autonomous driver is better and cause far less accidents than the humans.

(The small scale slow driving google cars with no steering wheel fall in this category).

Comment Yes, it's *giants* all the way down. (Score 4, Insightful) 123

Cue in citation about standing on giants' shoulders by Sir Isaac Newton.

Yup in reality - unlike what TV show and glamour media want you to think - there isn't such a thing as a "revolution" and "geniuses" in science.
Science is mainly an iterative process that build upon what was known and possible up to now and pushes the boundary a little bit further on each step.
It's not powered by "geniuses", but by brilliant humans that are able to notice what is available to them and how to combine these things to push the above mentioned boundaries.

That means that you can't trace back the "smartphone" as a single revolution started by one single person.
Countless scientists have each added their small brick to the Great Wall.

(e.g.: We could also add Volta : all current gizmo are electricity powered).

The flip side of this is that geeks and nerds tend to never be amazed by new technology.
We tend to realise that the latest over hyped and marketing pushed "revolution", is basically an evolution of what we've done in the past decade, only a tiny bit better.
(Nope, Apple's iPhone didn't start the smartphone. Only the mass-marketed smartphone craze. Idea of portable computers have been in the wild for quite some time with companies producing PDAs like Palm, Apple's own Newton, Psion, etc.)

The *yawn* reaction that you get from /. isn't merely condescending. It's just that we are better aware on which giant's shoulder the latest craze is standing.

Make all the rationalizations that you want, SCOTUS has already decided. This is not a matter of opinion or rightness, but fact. Non-citizens do not have constitutional rights. They do have human rights and any rights granted by treaty or specific laws, but constitutional rights are only guaranteed for citizens.

Fact: the consitution, in literal and clear words, say A.
Fact: a branch of the government, because it's more convenient for them, says B.

I demand rights I have, not rights a government wants me to have. That I cannot exercise those rights at present is why I'm complaining. And I'm among people who can, if we got off our asses, fight back: while we can't fight the way the congresscritters prefer, by the Golden Rule, as we don't have the gold, we can research ways and educate people how to get your data unmolested in face of unlawful searches and forced password exposure.

Americans should not be subject to unreasonable searches and seizures.

There are so many free sources of news, it may be impossible to sell it in the near future.

But how do those news sources get filtered and curated? The problem today is that there is so much news that you can find someone writing absolutely any story you want, regardless of the facts, and regardless of the relevance or importance.

It's a tool developed for internal, corporate users, to make Netflix's own operations more secure. They've decided to open source it, probably in hope that others will have good ideas to make it better.

Worse than that; in all likelihood.

While adoption has been patchy; the 'trusted computing'/TPM guys definitely have what it takes to deliver a cryptographically locked bootloader and a variety of other powerful-and-somewhat-creepy capabilities; so anyone who gets onboard with this will presumably move from shipping hardware with shitty firmware that doesn't get patches to shipping hardware with shitty firmware that doesn't get patches and cannot be fixed or replaced even if you have the requisite expertise with that platform. The sort of 'support' that bootloader locked android devices get now. Far too insecure to be remotely safe; far too secure for mere mortals to reflash the firmware with something else without a particularly elegant 'trustzone' compromise or hardware attacks.

I hardly mean to suggest that OpenWRT will save IoT or anything(IoT needs a lot more saving than is probably possible for anyone; and vendors are spitting out unsupported hardware far faster than 3rd parties and mainline kernel support can catch up); but if you think shoddy firmware is bad; it's hard to get excited about shoddy firmware that is effectively impossible to replace even for devices based on well supported hardware.

Yep. Exactly. Gotta love government IT workers!

I love my government IT job. After years of working for Fortune 500 IT teams, I'm finally working with the best pros in the industry. ;)

Second best.

I spent 15 years as a consultant, working with both fortune 500 companies and government agencies. Government agencies tend to have one of two personalities; either they're quite good or they're horribly bad. Sounds like you got into a good one. Corporate IT departments of non-IT companies tend to be more middle of the road, though variance is huge. But the top tier information technology companies tend to have almost uniformly excellent people.
